Osburn Fireplace Inserts

How Osburn wood inserts heat your fireplace

A closed glass door and clean-burning firebox make your existing masonry fireplace a source of wood heat. Your chimney usually needs a steel chimney liner, sold separately. Check each page for liner hookup parts. A faceplate closes the gap around the insert. Pick the size on the page. All models burn dry seasoned firewood, meet current EPA clean air rules and heat with no electricity. Only the blower plugs in.

Frequently asked questions

What is the difference between the Osburn 1700 and 2000 inserts?

The 1700 is rated for about 500 to 1,800 square feet, with a cast iron door and burns up to 7 hours. The 2000 covers about 500 to 2,100 square feet, with steel trim around the glass door and burns up to 8 hours. Both include a blower. Both offer a faceplate in regular or large and door trim in black or brushed nickel. Measure your fireplace opening and call us if you are between the two.

What is the advantage of installing a wood insert into a masonry fireplace?

An open fireplace sends most of its heat up the chimney and pulls warm room air with it. An insert adds a closed glass door and clean-burning firebox, heating the room for hours while burning less wood and producing less smoke. The blower pushes warm air into the room.

Can I turn my Osburn wood stove into a fireplace insert?

No. A freestanding stove is not built or tested to sit inside a fireplace. Removing its legs or pedestal does not make it an insert. Choose a separate Osburn fireplace insert made for that job, and call us with your opening measurements to talk through the size.

Does an Osburn fireplace insert have an ash pan?

No. Ash stays in the firebox for scooping into a covered metal ash bucket between burns. Owners on Reddit advise emptying it often because ash and coals can tumble forward when the door opens. Let the fire burn down to coals, open the door slowly and clear ash before it builds up against the door.

How do you keep the glass clean on an Osburn insert?

Owners on Reddit advise keeping wood back from the glass to prevent overnight clouding. They open the air control fully for the first morning fire so heat burns off the film. Burn only dry seasoned firewood. Ask us for the manual's firebrick diagram if you are placing the bricks yourself in your Osburn fireplace insert.
